Answer:
About 2 liters
Explanation:
Since 1 gallon equals 3.785 liters, you figure out how many liters per week she uses by 3.785 x 0.75 which is 2.83875. Then divide that by 7 which is 0.405535 liters per day. Then multiply that by 5 days which is 2.027 liters in 5 days.
A dependible common measurement
H = 1.008
S = 32.066
F = 18.998
O = 15.999
(1.008 x 2) + (32.066 x 2) = 66.148 g/mol
(1.008) + (18.998) + (15.999 x 2) = 52.004
